JOHN A. ORIPE, OF MACON COUNTY, ILLINOIS.

SPECIFICATION forming partof Letters Patent No. 643,185, dated February 13, 1900.

Application filed December 16,1899- Serial No. 740,500. (No model.)

To all whom it may concern:

Beit known that I, JOHN A. ORIPE, residing in the county-of Macon, in the State of Illinois, (post-office, (Jerro Gordo,) have invented a certain new and usefnlWheel-Hnb, of which the following is a specification.

This invention relates to wheels having wooden spokes; and its object is to provide means for replacing spokes and tightening the same withoutcutting the tire. It is exemplified in the structure hereinafter described, and it is defined in the appended claim.

In the drawings forming part of this specification, Figure 1 is a representation of a hub constructed in accordance with my invention. Fig. 2 is an end representation of the body of the hub and the box thereof, the clamp-collar and binding-nut of the hub being detached therefrom. Fig. 3 is a longitudinal diametrical section through the hub. Fig. 4 is a representation of the inner surface of the clam pcollar.

The box 1 of the hub has an annular head 1. It is provided with radial ribs 2 and 3, and it is threaded at 4 on the end opposite head 1. The body 5 of the hub is bored to receive the box 1 and the head thereof. It is recessed in its inner surface to receive the ribs 2 of the box, and it has endwise-presented radial ribs 6, which occupy the space between spokes. The clamp-collar 7 is recessed in its inner surface to receive ribs 3 of the spindlebox, and it has endwise-presented radial ribs 8, which fit between the ends of ribs 6 when the different parts of the hubs'are assembled. The binding-nut) is internally threaded to screw onto the threaded end of the box, and it has wrench-seats, as 10, in its flanged end.

The body, the clamp-collar, and the binding-nut are internally ooextensive'with the box and they conjoin to form the hub. The

spokes are seated in the recesses between ribs 6, and they are clamped firmly against lateral swing by the ribs 8 of the clamp-collar.

When a spoke is to be replaced, the binding-nut is unscrewed, the clamp-collar is removed, and the spokes are moved out of and into place through the side openings disclosed by the removal of the clamp-collar.

Spokes that require lengthening are wedged outward by wedges inserted between the ends of the spoke and the box, and spokes that require lateral reinforcement may be braced by strips inserted between ribs 8 and the sides of the spokes.

The spindle-boxes are threaded right and left, the same as the spindles, and in addition to this they may be held against accidental unscrewing by removable pins, when desired.

The ribs 2 hold body 5 from turning on the box and ribs 3 effect the sameresnlt with regard to the clamp-collar, so that torsional stress is equally divided on opposite sides of the spokes.

I claim- A hub comprising a box, threaded on one end and enlarged at theother end, a body on the enlarged end of the box having endwiseextended radial ribs defining the spaces between spokes, a clamp-collar fitting on the box and having endwise-extended radial ribs normally fitting between the ribs of the body, and a binding-nut screwed onto the threaded end of the box and against the clamp-collar, substantially as described.

In testimony whereof I sign my name in the presence of two subscribing witnesses.

JOHN A. CRIPE.
